Based on my fork of the repository and the original project which is hosted on google code
If this patch helped you, and you are happy with the result you could consider making a little donation to my PayPal account on (email found here: http://minimind.nl/paypal.html)
To resolve issues with copy paste run:
sudo update_dyld_shared_cachein the terminal.. from patch v4 and later this is already ran after patching but it might need to be run AGAIN after reboot.. some testing needed.
This patch needs MD5's to identify IOKit and Nvidia driver files, if your version is not yet added to the script you can run "XXXX-patcher.command md5" and post them in a new issue, this way i can add them.
If you have a new version of IOKit or Nvidia driver that is not yet supported you can run the command and choose the patch version yourself. for Nvidia there are now 2 versions, so most likely you need v2 for IOKit there are 6 versions so for new IOKit's you most likely need v6. use the command like XXXX-patcher.command patch v6 Most of the time this will work, but use this function carefully.
The table might not be fully correct, and not all Macs are supported by this patch.
| OS X <= 10.11 | macOS >= 10.12 | |
|---|---|---|
| Intel HD Graphics | IOKit Patcher | CoreDisplay Patcher |
| Nvidia Desktop Graphics | IOKit Patcher | CoreDisplay Patcher |
| Nvidia Mobile Graphics | IOKit Patcher & Nvidia Patcher | CoreDisplay Patcher & Nvidia Patcher |
| AMD Graphics | N/A | N/A |
Everywhere where you see ~/Downloads/XXXX-patcher.command you can add
before you start make sure SIP is disabled. (Info about SIP)
Download the patch(es) you need to your downloads folder: (IOKit, CoreDisplay, Nvidia)
open the Terminal (found at /Applications/Utilities/Terminal.app)
run chmod +x ~/Downloads/XXXX-patcher.command (this makes the patch executable)
run the script ~/Downloads/XXXX-patcher.command
follow the instructions and fill you password when asked for
(if you need more than 1 patch, go back to step 3 here and continue with the next patch there)
reboot your machine
Next steps are not necessary for everyone:
extra functions: ~/Downloads/XXXX-patcher.command md5|status|patch (v1-vX)|unpatch|help for instance used like: ~/Downloads/IOKit-patcher.command patch v7 or ~/Downloads/Nvidia-patcher.command unpatch
If you wan't to request new functions for this script feel free to open an issue with the request.
First make sure SIP (System Integrity Protection) is turned off for this to work.
You can disable/enable this only when you boot into the recovery partition.
If you booted into the recovery partition and open the terminal you use csrutil disable to disable, csrutil enable to enable and csrutil status to check the status of SIP you can also check the status on your normal system.
the changes to SIP are only visible in the terminal after a reboot, so it will still notify you that SIP is on when you disable it and run csrutil status right after it.
SIP can safely be enabled after the patch of the IOKit, if you also want to use an Nvidia/AMD driver that has been patched you need to keep SIP disabled. this is because SIP will not allow you to run drivers which have a broken or no codesignature. by patching the driver we obviously break the codesignature. kexts are not signable by anyone but apple and trusted parties. so SIP needs to be off for them to load. IOKit is not a kernel extension and therefore must be codesigned to run, this is done with the wildcard certificate, unique to everyone. even with SIP disabled the IOKit will not run without this new codesignature. the script takes care of the codesigning of the IOKit.
